High-energy 3-4 friction clutch pack for GM 4L60 and 4L60E rebuilds, rated to 800F so the 3-4 clutch stops burning up under load.
If your Silverado, Sierra, Tahoe, S10, Camaro or Corvette is flaring on the 3-4 shift, slipping in overdrive or has dropped third and fourth entirely, the 4L60E needs a full set of frictions, not just one pack. Raybestos Powertrain RCP96-087 is that set. Raybestos catalogs it as a friction clutch pack module for the GM 4L60 and 4L60E from 1987 on, made in the USA, and its standout feature is the 3-4 clutch: six high energy frictions with a hardened core in place of the standard paper plates. Every other clutch in the unit gets OE replacement tan frictions in the same box.
Per the Raybestos catalog page, the module contains 24 friction plates for five clutches:
It is frictions only. Steels, seals, pistons, gaskets and the filter come from a separate overhaul kit or your old unit if the steels measure flat and unscored.
The 3-4 pack lives in the input housing. It applies on the 2-3 upshift and stays on through fourth, so on any highway trip it is carrying engine torque the whole time. Sonnax lists the stock 700-R4 and 4L60E 3-4 pack at five or six frictions depending on application, fewer than the seven used in the later 4L65E and 4L70E, and calls the weak factory backing plate a leading cause of 3-4 distortion and burnup. That is why this is the pack that usually goes first, and why a hardened-core high energy plate is the logical upgrade when you are already rebuilding. Six 3-4 frictions in this kit matches the larger stock stack; V6 units with five plates need the stack set to your housing.
A stripped sun shell can also leave a truck with no 3rd or 4th, so do not assume the clutches until the unit is apart.
Pull the pan and look. Fine brown or black friction dust confirms clutch wear; chunks of metal mean hard parts are damaged as well. Sonnax traces most burnt 3-4 clutches to low line pressure or a 3rd-gear oil leak, so air check the input housing, inspect the 3-4 piston for cracks, and check the pump before you trust new plates. Our 3-4 clutch failure diagnosis guide walks through those checks, and the friction count and upgrade guide covers stack-ups if you want more plates than stock.
Raybestos lists RCP96-087 for the GM 4L60 and 4L60E from 1987 on. That covers late 700-R4/4L60 hydraulic units and the 4L60E in 1993-2013 Chevrolet Silverado 1500, Tahoe, Suburban, S10, Blazer, Camaro and Corvette, and the GMC Sierra 1500, Yukon and Sonoma. The reverse input frictions are the 2nd design that started in 1987, so a pre-1987 700-R4 is not a match. If you are unsure, count the plates in your old packs or send us the year and VIN. See every part for this unit on our 4L60E shop page.
Drive it gently for the first few hundred miles so the new frictions bed in before you tow.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Raybestos lists it as a complete friction module: 2 overrun, 5 low and reverse, 4 reverse input, 5 forward and 6 high energy 3-4 frictions. The 3-4 plates are the upgraded part; the rest are OE replacement.
No. It is friction plates only. Pair it with an overhaul kit for seals and gaskets, and reuse steels only if they are flat, unscored and not blued.
Raybestos lists it for the GM 4L60 and 4L60E from 1987 on, which includes the 1995 truck 4L60E. Count your 3-4 frictions on teardown, since some V6 units used five instead of six.
It carries engine torque in third and fourth, the stock pack has few plates and the factory backing plate can flex. Low line pressure or a 3rd-gear oil leak makes it slip and overheat.
Dexron VI ATF. Soak the new frictions in the same fluid for at least 30 minutes before assembly.
It is a good choice for a stock or lightly modified build because of the high energy 3-4 plates. For big power, look at a higher plate-count 3-4 setup and a stronger backing plate.
